Applications:
       Multi-electrode resistivity method receives more and more attention by research institutes and colleges in China due to its special action in the fine exploration. Much research has been done these years, and it is becoming perfect.
　　According to the needs of users, our institute develops WGMD-3 multi-electrode resistivity measurement system by taking the WDJD-3 mutil-function digital DC induced polarization resistivity instrument as the control part, WDZJ-3 as multiplex electrode converter. Further more, we cooperated with other institutes and developed the BT-WYS electric Processing Specific Program that makes the interpretation more and more convenient and visual.
　　The instrument can be widely applied in metal and nonmetal mineral resources detection, city geophysical exploration, railway and bridge exploration, and other application. It is also applied in hydrologic geology and engineering geology such as searching for ground water, locate base of dam and flood protection levee incipient fault, can still used for geothermal prospecting.

Features,Composition & Functions
　　

      Principal machine of the system is of multiple uses. It can be used not only for conventional DC electric survey, but also for multi-electrode resistivity survey. It has the features of high accuracy, fast speed survey, large memory capability, Chinese character menu session, easy operation, and flexible multiplex electrode converter. Its self-check function can even locate each switcher. WGMD-3 system can connect many multiplex electrode converters in series to compose cascade by communication cable.
